Free Bitcoin is availble. There are faucets that allow you slowly accumulate small amounts. These sites are ones that I use, and have cashed out unless specified otherwise. These sites come and go. I will only promote the ones that pay. There are ads and links on these that I cannot endorse. Never believe adds that claim you can get more that small amounts of interest. Anything over 5% is a scam

Yet Another Bitcoin Lottery. This is fun. I have never cashed out, but have had some good wins that I lost. If you make a deposit the cash out is low, but it gives .00005 btc to play with that refreshes quickly
